radiotoxicadj.

Brit.

/ˌreɪdɪəʊˈtɒksɪk/, U.S.

/ˌreɪdioʊˈtɑksɪk/

Origin: Formed within English, by compounding. Etymons: radio- comb. form², toxic adj.

Etymology: < radio- comb. form² + toxic adj.

Biology.

1. Designating the damaging effects on living cells and tissues of ultraviolet radiation; relating to or characterized by such effects. Now disused.

ΚΠ

1934 Chron.-Telegram (Elyria, Ohio) 6 Sept. 4/1 Dr. Meier has grouped the responses she obtained in two categories—radiotoxic, spectral sensitivity and radiotoxic virulence.

1940 Sci. Monthly June 524/1 The intensities of 20 different wave-lengths ranging from 2250 A to 3022 A were carefully measured and their effects studied with respect to..their radiotoxic virulence or speed of effectiveness in killing the cells.

2. Designating the toxic or other damaging effects on a living organism of a radioactive substance present in its tissues; relating to or characterized by such effects.

radiotoxic1950

1950 Nucl. Sci. Abstr. 4 398/1 Rat erythrocytes were irradiated with 6,030r and then injected subcutaneously..in order to determine the severity and nature of radiotoxic effects.

1975 Nature 27 Mar. 278/3 The dose limit for bone is based on uniformly deposited ²²⁶Ra: but Pu, collecting at the bone surface, is considered ∼5 times as radiotoxic.

1998 G. A. Kreps in E. L. Quarantelli What is Disaster? 51 Most of the radionuclides released following the accident had a very short life wherein they could cause medical problems (a few days or weeks). But others can remain radiotoxic for a very long time (from many decades to centuries).

Derivatives

ˌradiotoˈxicity n. [ < radio- comb. form² + toxicity n., after radiotoxic adj.] the state or condition of being radiotoxic.

1946 D. Antony et al. Radiotoxicity of Injected Sr⁸⁹ for Rats, Mice & Rabbits (U.S. Atomic Energy Comm. Rep. MDDC 1540) 6 Radium, hitherto the only substance of which the radiotoxicity had been extensively studied.

1992 Cancer Res. 52 5752 Chinese hamster ovary cells not expressing estrogen receptor showed little sensitivity to the radiotoxicity of the ¹²³I-labeled estrogens.
